Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional coupling systems are used to connect suction apparatus components, then the device complexity is reduced, but the connection stability and reliability deteriorate
Solution Approach 1:
The patent combines multiple coupling functions into a single integrated coupling element. The coupling element integrates the connecting piece, guide contours, and electrical plug-in units into one unified structure, eliminating the need for separate coupling mechanisms while achieving stable mechanical and electrical connections simultaneously.
Solution Approach 2:
The coupling element serves multiple functions: it provides mechanical connection through the tubular connecting piece, ensures proper alignment through guide contours, transmits electrical energy through plug-in units, and prevents relative movement through form-fit engagement. This multi-functional design improves reliability without proportionally increasing complexity.
2Stability of the object's composition
If a simple coupling mechanism is used, then the ease of operation is improved, but the prevention of relative movement deteriorates
Solution Approach 1:
The guide contours are designed to preliminarily guide the coupling elements into the correct position and orientation before the final form-fit engagement occurs. This preliminary alignment action ensures stable connection while requiring minimal operational effort from the user, as the guide contours automatically facilitate proper positioning during the coupling process.
3Reliability
If electrical plug-in units are integrated into the coupling element, then the reliability of electrical energy transmission is improved, but the device complexity increases
Solution Approach 1:
The electrical plug-in units are merged with the mechanical coupling element, creating a single integrated component that handles both mechanical connection and electrical transmission. This integration ensures that mechanical and electrical connections are established simultaneously, improving reliability while the unified structure minimizes the actual increase in complexity.
4Stability of the object's composition
If a robust coupling system with form-fit engagement is used, then the prevention of relative movement is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The coupling element is designed with distinct functional segments: the tubular connecting piece for mechanical engagement, the guide contours for alignment, and the electrical plug-in units for electrical connection. This segmentation allows each feature to be manufactured and assembled independently, simplifying the overall manufacturing process while maintaining the robust form-fit engagement for stability.

AI summary
A coupling system for connecting different suction air-guiding components of a suction apparatus includes a first coupling element having a tubular connecting piece and a second coupling element having a tubular receiving region for the connecting piece. The first coupling element includes a first plug-in unit and the second coupling element includes a second plug-in unit, which is configured so as to form an electrically conductive plug-in connection with the first plug-in unit of the first coupling element. The connecting piece has a guide contour that faces the first plug-in unit, and the second coupling element has a guide contour that is complementary thereto and that faces the second plug-in unit. A first coupling element and a second coupling element for a coupling system, as well as a suction air-guiding component for a suction apparatus and a suction apparatus, are also provided.
